The new music matching feature gets your songs into your online music library on Google Play much faster. Google scans your collection and rebuilds it in the cloud - all for free. The music is streamed back to you at up to 320 kbps.
This feature is live today for people in the US, following our European launch last month.
The service is similar to Apple's iTunes Match, which includes online storage for 25,000 songs. Google allows storage for 20,000 songs and allows users to re-download the songs only at the same quality as they were at previously. Apple charges $25 a year for its service.
